CARBURETER.

SPECIFICATION forming part of Letters Patent No. 689,460, dated December 24, 1901.

Application filed March 23,1901. Serial No.52,557. (No model.)

To all whom, it may concern: Y utilize volatile hydrocarbon of any nature.

Be it known that we, JAMES G. CLARK and Combined with the'tank 3 is means for forc- GRQVE COTHRAN,citizens of theUnited States, ing air therethrough-to become enriched with 55 residingatSummitville,in the countyof Madicarbon, so as to produce a gaseous mixture 5 son and State of Indiana, have invented cerfor use either as an illuminant or for heating tain new and useful Improvements in-Carbupurposes. A blastpipe 5 passes centrally reters and We do hereby declare the following through the upper end of the tank, to within to be a full, clear, and exact description of the a short distance of the bottom thereof, and is 6o invention, such as will enable others skilledin provided at its lower end with a series of ra- Io the art to which it appertains to make and dial branches 6, perforated along their upper use the same. sides for the escape of the air in minute jets.

This invention relates to the production of This blast-pipe 5 may communicate With an gas from crude petroleum for illuminating air-pump 7, a steam-generator, or any means 65 and heating purposes, the object being to profor creating a current through the carbureter.

It is not necessary to heat either the The carbureter consists of atank or recepcarbureter or the coil 12; but superior reroo tacle 3, in which the gas-producing agent 4 sults are attained by heating these parts.

A valve 19 is provided in the upper portion of the eductionpipe 18 to cut off communication between the pipe 18 or to regulate the outflow of the sedimentary matter from the carbureter. When the valve 19 is open, the residue or sediment precipitated or collected at the bottom of the tank 3 passes off through the pipe 1S into the tus is in use, there isa currcntof the gaseous mixture through the pipe 13, and when the Valve 19 is open this current creates a vacuum or suction in the pipe 18, which, supplemented by the downward pressure of the gaseous mixture upon the gas producing agent 4:, exerts and produces an outfiow of the sedimentary matter through the pipe 1S into the pipe 13, and this matter commingling with the gaseous mixture is carried along thereby to the heater and is converted thereby into vapor or gaseous form for subsequent use for heating, lighting, or any industrial purpose for which gas is applied.

Having thus described the invention, what is claimed as new is- The herein-described gas-producing apparatns, comprising a tank, an incased heatingcoil, a valved pipe connecting the upper portion of the tank with the heating-coil, a blastpipe communicating with the lower portion of the tank and having perforate branches at its loworend for distributing the blast through the gas-producing agent, a valved ednctionpipe extending,r through the tank to within a short distance of the bottom thereof and having connection at its upper end with the pipe connecting the heatingcoil with the said tank, and a distributing-pipe having connection with the opposite end of the heating-coil and provided with burners for heating the said coil and tank, substantially as set forth.

In testimony whereof We affix our signatures in presence of two witnesses.
